Wait a minute, you said everything I was seeing in your #1 pic was all one single residence.
Now we find out it’s two residences? One mans wall is another man’s bedroom, one man’s floor is another man’s ceiling.
Like I said, they’re all very similar to apartments or civilian barracks, with nice facades. You made my point better than I.
A townhome, however, has only units to your left and/or right (and end units only has one touching unit), typically only has 4-6 units per "building," is much larger than an apartment (usually about the size of a starter single family home), nicer finish inside, and usually has a backyard or at least a very large patio with some grass. They are two very, very different experiences. A townhome experience, especially for those without kids, is not significantly different experience than a small single family home community where the lots are only 0.15-0.2 acres, while a condo is massively different. There is a reason townhomes sell and rent for significantly higher than condos do.
